Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions. Here’s the Haleakala Crater webcam on Maui – if it’s working.
Light to moderately strong trades through mid-week
Windward showers at times locally…some afternoon
upcountry showers here and there too

We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.
~~~ Hawaii Weather Narrative ~~~
The trade winds will continue blowing, although a bit lighter through mid-week…then increasing slowly Thursday onwards. Here’s a weather chart showing two near 1026 millibar high pressure systems located far to the northwest and northeast of the islands. There are also many low pressure systems, and low pressure troughs in the central Pacific now too. Our long lasting trade wind weather pattern will continue through this new week…becoming moderate to locally strong and gusty by the weekend.
Generally favorable weather prevails, with windward showers at times...with a few upcountry afternoon showers too. Satellite imagery shows scattered low cloud patches over the ocean surround the islands, being carried into the windward sides at times. We see one large patch of clouds moving into the Big Island and Maui County, which will bring an increase in showers to the windward sides of those islands tonight. The leeward beaches will be mostly clear to partly cloudy during the mornings…with cloudy areas and localized showers in the upcountry areas during the afternoon hours. At the same time, we can see high level clouds to our west…and just to the southeast of the Big Island. Here’s the looping radar image, showing showers falling over the nearby ocean, and along the windward coasts and slopes in a few places.
Tropical depression 03C is now active in our central Pacific. There’s still a tropical disturbance in our central Pacific waters as well, which has a low 10% chance of developing into a tropical cyclone over the next couple of days…to the southeast of the Big Island. Here’s a satellite picture, showing this area circled in yellow, along with TD 03C. There’s no danger of any tropical systems having a negative impact on our islands at this time. I’ll be back with your next new weather narrative early Tuesday morning. By the way, Tuesday evening will be the time of our August full moon. I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.

Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.
Showers and thunderstorms associated with a disturbance about 700 miles southeast of Hilo Hawaii are showing limited signs of increased organization this evening. Strong upper level winds are expected to prevent significant development within this area through Tuesday, but winds aloft may weaken Wednesday. This system has a low chance, 10 percent, of becoming a tropical cyclone during the next 48 hours.

Interesting: How much will climate change cost coastal cities? – Global damage from flooding could cost coastal cities as much as US$1 trillion per year — and developing countries will be hardest hit, a study warns.
According to the paper published today in Nature Climate Change, a “risk sensitive planning” strategy is needed to protect coastal cities, which are increasingly at risk because of climate change, subsidence and a growing population.
The researchers looked at the 136 largest coastal cities in the world and found that cities in developing countries are particularly vulnerable to flood losses as they often lack resources for long term planning.
“No city is doomed, but we have to expect huge disasters in the future. And better international coordination to provide support for the affected countries is really important,” says Stephane Hallegatte, senior economist at the Sustainable Development Network of the World Bank and lead author of the study.
“For each city we assessed the total cost of potential damages,” says Hallegatte. “But we also looked at the relative losses, comparing the absolute cost to the city’s gross domestic product, to give an idea of the actual vulnerability of each city.”
Among the top 20 cities with highest relative losses in proportion to their gross domestic product in 2005, only three are located in developed countries. The list is topped by cities such as Guangzhou in China, Guayaquil in Ecuador, Ho Chi Minh City in Vietnam, Abidjan in the Ivory Coast, Zhanjiang in China and Mumbai in India.
